Total hip replacement in dogs with contralateral pelvic limb amputation: A retrospective evaluation of 13 cases

Abstract

Objective: To report the clinical characteristics, surgical management, and medium-term outcomes of total hip replacement (THR) performed in dogs with previous contralateral pelvic limb amputation. Animals: Thirteen client-owned dogs. Study design: Multi-institutional retrospective clinical study. Methods: Data recorded from medical records included signalment, indication for amputation and THR, and surgical complications. Implant positioning and complications were assessed on radiographs. Clinical outcomes were evaluated during follow-up examinations by one of the authors and through a mobility-and lifestyle-based questionnaire completed by owners. Results: All 13 dogs had satisfactory clinical results at follow-up a median of 3 months (range, 2-36) after THR. No postoperative luxation was recorded. Four dogs had minor complications that did not require additional treatment. The only major complication was one failure of osseointegration of a cementless acetabular cup, and it was successfully revised.

Total hip replacement in a cat with contralateral pelvic limb amputation

“…This case report documents an acceptable long-term outcome (follow-up of over 12 months) 10 without complications of a cemented hip replacement in a cat that had previously undergone contralateral pelvic limb amputation. Total hip replacement in dogs with previous contralateral amputated pelvic limb has been described in three studies; 8 , 11 , 12 one reported that 4/9 dogs required surgical revision after luxation of the THR. 8 …”

Clinical evaluation of total hip arthroplasty for osteoarthropathy secondary to septic hip arthritis

“…It has been confirmed that the nerve damage caused by THA is greatly related to compression, traction and ischemia according to extensive researches focused on the etiology of nerve damage. [17] Therefore, much attention should be given to the protection of nerves and blood vessels when balancing the length of the limbs. [18] In this study, the shortened limbs were significantly improved after operations.…”

“…[1][2][3][5][6][7][8][9][10][11] Prior studies evaluating the clinical outcome of THA in dogs have reported a complication rate ranging from 4 to 34%. [1][2][3][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23] Postoperative luxation is the most widely reported complication of THA, occurring in 1 to 20% of cases. 2,6,13,15,19,21,[24][25][26][27] Improper orientation of the acetabular component has been identified as an important contributing factor for postoperative luxation in THA in the dog.…”
